3FEGIFICATION forming part of Letters Patent No. 737,944, datedSeptember 1, 1903.

Application filed March 13, 1903. Serial No. 147,600. (No model.)

To a, whom it may concern:

Be it known that 1, DAVID LUBIN, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in the countyand State of New York, haveinvented a new and Improved Power Device, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in power devices particularlyadapted for drawing a cultivator or other agricultural implement throughthe ground to finely pulverize or break the earth around and betweenrows of plants or to draw such implement through unplanted ground, anobject being to provide a device of this character designed to beoperated manually and by means of which a comparatively heavy tool maybe operated with but verylittle manual exertion and digging deeply intothe ground.

I will describe a power device embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a power device embodying my invention,showing it in connection with an agricultural implement. Fig. 2 is afront elevation of the device. Fig.3 is a detail illustrating a meansfor attaching a draw-line to the winding-drum. Figs. 4 and 5 arerespectively side and front elevations of a modification. Figs. 6 and 7are respectively front and side elevations show- Fig. '7 is an elevationshowing a modification. Fig. 8 is a perspective view showing ananchoring device that may be used in lieu of that shown in Figs. 6 and7. Figs. 9, 10, and 11 are side elevations showing other modifications,and Figs. 12 and 13 are front and side elevations showing a gearmechanism that may be employed for the winding-drum.

Referring first to the example of my improvement shown in Figs. 1 and 2,1 designates a standard having at its upper end a yoke 2, in which ashaft 3 of a winding-drum 4 has its bearings, and on the opposite end ofthis shaft are the operating-cranks 5. Attached to the lower end of thestandard is a frame comprising downwardly extended members 6 '7, whichare spaced apart, so as to straddle plants in a row when it is desiredto draw an implement over the ground to cultivate the ground at thesidesof the plants. Attached to the lower ends of the frame members 6 7are horizontal bars 8, designed to rest upon the ground. These barsextend forward and rearward, so that the device will be held firmly fromtilting forward or rearward when in operation. The said bars Sareconnected to the upper portion of the frame by means of braces 9, andbraces 10 connect the rearward extensions of said bars with said frame,and braces 11 firmly connect the frame with the standard. Pivotallyconnected to the members 6 7 of the frame are rearwardly extended arms12, which are guided in their up and down movements by uprightsl3,secured to said bars, and inwardly-extended pins 14 on said uprightsprevent the arms from moving too far upward. Anchoring devices arecarried at the ends of these arms 12. As here shown, these anchoringdevices consist of teeth 15, removably secured in clips 16, attached tothe arms. By this arrangement as a set of teeth becomes worn out a newset may be readily inserted, or the teeth may be adjusted vertically andheld by means of setscrews 17, as occasion may require. From the drum 4a draw-line or cable 18 extends down and around a pulley 19, supportedin the upper portion of the frame members 6 7, and from this pulley thedraw-line extends to a connection with an agricultural implement hereshown as a cultivator 20, designed to cultivate the ground on oppositesides of a plant and the construction of which need not be furtherdescribed herein, as itis described and claimed in another applicationfiled by me under date of February 3, 1903, Serial No. 143,955. As aconvenient means for attaching the end of the draw-line 18 to thewinding-drum 4 I provide one of the flanges 21 of the drum with twoholes 22 23, and the end of the rope is passed from the inside outwardthrough the hole 22 and thence inward through the hole 23, where it isknotted, as indicated at 24 in Fig. 3. Other means of securing thedraw-line of course may be employed without departing from the spirit ofmy invention.

In the operation of this device when the agricultural implement is at astandstill the anchoring devices are to be drawn out of the ground andthen the power device moved rearward to any desired distance-say onehundred feet. Then after placing it in position one of theanchoringdevices is to be forced into the ground by one foot of theoperator, and then the other anchoring device is to be forced into theground by the other foot of the operator. The operator then whilestanding upon the upper ends of the anchoring devices or on the arms 12will operate the drum 4, drawing the implement forward until it reachesa point near the power device, when said power device is to be againmoved back ward and the operation continued.

In the example of my improvement shown in Figs. 4 and 5 the standardcomprises a frame consisting of front members and the rear members 26and the bottom rearwardlyextended members 27, the parts 25 and 26 of aside being divergent from the top downward, and in the upper portion thewinding-drum 4 is mounted.

It may be here stated that in this example I provide a clutch connectionbetween the crank-handles and the drum-shaft. As here shown, this clutchconsists of a lug 28 on the shaft designed to engage in recesses formedin the crank-handles. When the cranks are moved into engagementwiththese lugs 28, the drum will be operated by said handles; but whenthe machine is moved rearward and the drawline unwinds the handles willbe moved out of engagement with said lugs, so that the drum may berotated freely.

Anchor-carrying arms 29 have swinging connection with the members 27 ofthe frame or standard, and they are guided between straps 30 and therear members 26, and carried by these arms 29 are the teeth 15, likethose first described. The standard is supported at its front portion bywheels or rollers 31, so that it may be readily drawn over the groundwhen moving it rearward. The drawline 18 extends from the winding-drumaround a pulley 32, carried by a bar 33, adjustable vertically in slots34, formed in the members 25 of the standard. By this arrangement thepulley 32 may be adjusted to any desired elevation to cause the fronttines of the agricultural implement to dig more or less deep into theground. It may be held as adjusted by means of pins 35, passing throughperforations in the bar 33 and through perforations in the members 25.When the bar is in its uppermost position or approximately thereto, thedevice maybe used for straddling plants, as in the device firstdescribed.

In the example of my improvement shown in Figs. 6 and 7 a standard 36 isprovided at its upper end with a rearwardly-extended handle 37 and atits lower end with tines 38,

which are designed to be clamped between the clamp-bars 39 40 by meansof bolts 41, and the tines, it will be noted, extend slightly below saidbars, so as to engage in the ground and aid materially in the anchoringof the device. Attached to one of said members is a frame or casting 42,which has a rearward extension in which an anchor-carrying arm 43 ismounted to swing. At the end of this anchor-carrying arm is ananchor-tooth 44, and on the upper side of the arm is a footplate 45.This single tooth 44 in connection with the extensions of the tines 38will form an effectual anchor; but instead of the single tooth I mayemploy two teeth 46, attached to an arm 47, designed to be pivoted tothe frame or casting 42, and a part 48, receiving the connecting-bar ofthe teeth 46, forming a foot-plate. Also mounted in the frame or casting42 is a pulley 48, around which the draw-line 18 passes. In theoperation of this device when in position the projected ends of thetines 38 are to be forced into the ground, and then the tooth 44 or theteeth 46 are to be forced into the ground by foot-pressure, and thenwhile the operator is standing on the foot-plate the winding-drum may be0perated.

In Fig. 7 I show a device particularly designed for light work and inwhich the platform is omitted, and in lieu of the platform I employ anextension-handle 46, adjustable vertically on the standard. By graspingthis handle considerably above the drum the leverage or holding power issubstantially the same as pressure or weight on the platform.

The devices shown in Figs. 9 and 10 are designed to be used when thetool is to be drawn over ground in which there are no grown plants orbetween rows of growing plants.

In Fig. 9 a frame 49 is attached to the lower end of a standard 50, andon the crossbar 51 of this frame are the ground bearingarms 52, whichextend forward and rearward of said bar 51 and are suitably secured bybraces 53 54. The anchor-teeth 55 of this example are removably securedin castings 56, that may be attached to the rearward extensions of theparts 52 by means of bolts 57, or they may be attached to said parts 52forward of the standard 50 by passing the bolts through openings 58.Arranged in the frame 49 is a pulley 59, around which the draw-line 18passes, the portion of said drawline between the pulley and drum beingextended along the rear side of the standard.

In Fig. 10 the standard 50 has a forwardlyextended yoke at its upper endin which the winding-drum is operated, and on the lower end of thestandard is a cross-bar 61, having upwardly and outwardly projectingarms 62, in which a pulley 63 for the drawline is supported. Attached tothe ends of the cross-bar 61 are ground bearing portions 64, whichextend rearward and forward of the standard and support theanchoring-teeth 55 at the rear end.

In Fig. 11 I have shown a device on which the operator may sit to firmlyhold the anchoring devices in the ground. In this example the lowerportion of the standard 50 is attached to a ground-frame 65, on theforward extensions of which ground-wheels 66 are mounted and on the rearends are the anchoring-teeth 55. A seat 67 is supported from the frameby standards 68 69. In this example a lower pulley 70 is located at thelower end of the standard below the frame, so that a slight downwarddraw may be imparted to the agricultural implement. This pulley,however, is removable, so that it may be placed at a higher point on thestandard when the machine is used to straddle plants. The operation ofthis device is substantially the same as hereinbefore described.

In Figs. 12 and 13 I have shown a construction by means of which amaximum of power may be imparted to the winding-drum by a minimum ofmanual exertion. In this example a winding-drum 71 is mounted in a yoke72 on the upper end of the standard, and on one end of the drum is agear 73, engaging a pinion 74c, loosely mounted on a power-shaft 75,mounted to rotate in the yoke 72 and to move longitudinally therein. Onthe shaft 75 is a clutch member 76, and on the pinion 7a is a clutchmember 77. While winding the drum the shaft 75 is to be movedlongitudinally to engage the member 76 with the member 77; but whenmoving the power device rearward to a new position the clutch membersare to be detachable, so that the drum may be rotated freely.

While I have shown a gear-wheel on the drum and a pinion on the shaft,it is obvious that this arrangement may be reversed without departingfrom the spirit of my invention.

It will be noted that in each example of my invention the pulley isarranged below the winding-drum, and therefore a direct pull is exertedon the implement, keeping it practically level with all its teeth in theground during its entire movement, which would not be the case were thecable extended directly from the drum or from a device above the drum,and consequently at a downward incline.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent-- l. A power device, comprising a standard, awinding-drum supported by the standard, a pulley below the drum, and ananchoring device extended rearward from the lower portion of thestandard and adapted to be held in the ground by manual pressure.

2. A power device, comprising a standard, a winding-drum supported bythe standard, and an anchoring device arranged rearward of the standardand having a vertically-swinging movement.

3. A power device, comprising a standard, a frame on the lower end ofsaid standard comprising spaced mem bers, bars attached to the lowerends of said members and extended forward and rearward therefrom, armshaving vertical swinging relation to the standard, anchoring devicescarried by the arms, and a winding-drum at the upper portion of thestandard.

4. A power device, comprising a standard, a winding-drum at the upperportion of the standard, a pulley at the lower portion of the standard,a draw-line extended from the drum around saidpulley, a frame at thelower end of the standard comprising spaced members, bars attached tothe lower ends of said members and extended forward and rearwardtherefrom, rearwardly-extended arms mounted to swing, andanchoring-teeth removably connected to said arms. I
